Data Recovery for Corrupted or Infected Backup Systems
The increase in ransomware cases targeting backup files means that organizations that suffer a malware attack can no longer rely on backups to restore important data from critical systems.
We have developed specialized software that allows us to restore critical data files from ransomware-infected backup systems that would otherwise be permanently irretrievable. We’ve had multiple successful recoveries of malware-infected data even when the customer believed they were out of options.
How Can Backup Systems Be Damaged by Malware?
Backing up your data is one of the best ways to protect your devices against data loss. But backup systems can also be infected. In fact, viruses and malware are a common cause of data loss in backup systems.
Viruses can cause a significant amount of damage to your devices, including backup devices, deleting or corrupting large amounts of data. Some malware, for example, is designed to delete or modify data simply to cause destruction, while ransomware encrypts data, making it inaccessible.
The good news is your data isn’t necessarily lost forever. If your data backup system has been damaged by malware, our data recovery experts can help you get your data back using our specialised software designed to restore critical data files from infected backup systems.
How Does Ontrack Recover Data from Infected Backups?
Restoring data from a corrupted backup can be extremely complex as backup data loss may occur at many different levels. For example, Ontrack had a customer that was a victim of a cyberattack on their 64 disk 110TB NAS. The data recovery challenge comprised 4 different RAID LUN configurations, many storage tiers including VMware Datastore, several corrupted 20TB+ VMs, and damaged backups. Ontrack was able to successfully recover the customer’s data relying on the vast amount of experience of our global team of data recovery experts combined with our patented technology. Our teams perform data recovery at all levels with engineers checking for errors at each level and working their way up.
Damaged Backup Recovery Case Studies
Ransomware Recoveries on Tape – Server and NAS Systems
The Client
International pharmaceutical company
Challenge
This customer suffered a cyberattack wherein the attacked volume was originally used to back up data to LTO8 tapes at regular intervals. Most of these backup tapes were in the tape library at the time of the incident and were quickly formatted by the attackers. However, the customer saved an original unformatted tape with a relatively old backup date, which was then completely restored to the now empty Windows volume with a total of 6 TB. Only then did the customer commission Ontrack to examine the data recovery options.
Additionally, the attack affected numerous European suboffices of the customer where there were predominantly QNAP NAS systems in use.
Solution
The HP server DL380 with the 55 3TB hard disks and LTO8 tapes were transported to Ontrack in Böblingen, Germany. During the diagnosis, a large number of the searched files were successfully found on the Windows volume using Ontrack’s proprietary tools and 27 records were extracted according to a priority list.
The restoration of the LTO8 tape partially overwrote some of the data sets and damaged the backup files. However, a large part of the data could still be repaired and extracted in several steps. At a later time, 19 significantly older LTO8 quick formatted tape backups were successfully recovered from the ransomware attack as well.
The QNAP NAS systems had stored virtual VMs under VMware, including backup VMs that were partially deleted or internally reformatted with another file system.
Result
Ontrack successfully restored complete backup data in 90% of the seven cases ordered.
